the red parking brake status light is
flashing. See your dealer. See Parking
Brake Light 0 123.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light is on, see
your dealer.
If the EPB is applied while the vehicle
is moving, the vehicle will decelerate
as long as the switch is held up. If the
switch is held up until the vehicle
comes to a stop, the EPB will remain
applied.
The vehicle may automatically apply
the EPB in some situations when the
vehicle is not moving. This is normal,
and is done to periodically check the
correct operation of the EPB system.
If the EPB fails to apply, the rear
wheels should be blocked to prevent
vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in the ACC/
ACCESSORY or ON/RUN/START
position.
2. Apply and hold the brake pedal.
3. Push down momentarily on the
EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by pushing
down on the EPB switch and holding
it down. Continue to hold the switch
until the red parking brake status light
is off. If either light stays on after
release is attempted, see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
DRIVING AND OPERATING
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive
away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life.
The EPB can also be used to prevent
roll back for vehicles with a manual
transmission taking off on a hill.
When no roll back is desired, an
applied EPB will allow both feet to be
used for the clutch and accelerator
pedals in preparation for starting the
vehicle moving in the intended
direction. In this case, there is no
need to push the switch to release
the EPB.
If parking on a hill, or if the vehicle is
pulling a trailer, see Driving
Characteristics and Towing Tips 0 276.
